I have a project that has been working completely fine in 4.25. Jumped into VR a couple days ago and the lighting for the right eye had all but dissapeared. It seems to be that there is no inderect lighting or GI.
I have tried re-building the lighting a number of times and none of my blueprints have changed. i have not altered any of the project setting either.
No solution from me, but I’m having the same issue in 4.25.4. Additionally, the left eye seems to have some ghosting going on. This happens in 4.26 preview 6 too - I have no idea how to figure it out.
As noted in the comments, I’ve been seeing this issue as well. I played around with a few settings and it seems that disabling screen space global illumination in the project’s properties solves this particular issue for me. Which is unfortunate, as it works pretty well otherwise.
After some further exploration, seems like quite a few of post process effects are behaving weirdly or not at in 4.25 and 4.26 preview 6. Anything involving raytracing (reflections, ambient occlusion, GI) is also broken and either not displayed or displayed with a strange color/hue drift - I see bright purple or rose colored ghosting on the right eye, whereas the left eye works OK.
Thanks for your answer on this, i tested out the screen space GI and that has worked in my case also. Very strange indeed. Hopefully this is something that Epic will fix before full release of 4.26.
I also have issues where shadows or reflections behave differently in the right eye (doesn’t render). Also things like lens flare don’t render in that eye as well. I’m on 4.27.2
